I don't mind most of the ideas suggested in the OP except for frozen and petrified. I think frozen would be better with something like "the target cannot act for this turn and gains only half of their normal action points" and petrify should prevent physical damage instead of magic damage. I feel very strongly that turning CC into buffs is a bad idea though as the game is already abuse-able enough without adding another layer of craziness that needs balancing.
